We have been using Corsairs DDR433 in our Athlon64 FX-51 and 53 test systems for the past few reviews. Based on our experiences with it we thought it was time to take a look at the memory and let you know if it’s worth considering for your socket 940 based system.

The Product:
The Corsair PC3500 Model we have is 100% tested to work at ddr433 (217mhz) with timings of 2-3-2-6. Additionally Corsair have SPD programmed it so that if your motherboard is set to SPD rather than manual timings the board will boot with the ram at 2-3-2-6 (200mhz) which is a very helpful feature as it saves any messing about in the BIOS.

The 2 sticks come packed in a rather flimsy packet considering the value of the parts within. Some sort of padding would be advisable in our opinion. The inner sleeve of the package contains detailed instructions in 5 languages, with pictures, on how to install the Dimm’s. The Sticks themselves are very well designed. Each one is covered by a heat spreader front and back along with a hologram sticker showing the details of the part.

As these parts are made for Athlon64 FX systems they are also Registered Dimm’s which use ECC when enabled by the user. As a further quality check I was pleased to see that Corsair verify that the ram meets standards in both ECC enabled and disabled modes.

The test system was built from scratch, a format of the hard drive was performed (NTFS) and then Windows XP was installed. Following the completion of the install the N-force drivers were installed. The only updates applied were SP1a and Direct X 9.0b. Following a reboot the Detonator 53.03 drivers were installed. Next the benchmarking tools were installed and finally the hard drive was de-fragmented. For all tests the Nvidia drivers were set to best image quality.

Good Benchmarking Practice:
Each benchmark was performed 3 times and the middle result for each resolution/setting is shown in the tables which follow. After changing any Anti-Aliasing (AA) or Anisotropic Filtering (AF) setting and before a benchmark was run the system was rebooted. All games/applications had their latest patches applied.
